CD214A-T5.0CALF Equivalent & Substitute Parts

Part Overview

The CD214A-T5.0CALF is a transient voltage suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection in surface-mount applications. This component features a 5V reverse standoff voltage, 9.2V maximum clamping voltage, and 44.6A peak pulse current capability in a DO-214AC (SMA) package. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD214A-T5.0CALF is determined by the following critical parameters:

• Voltage - Reverse Standoff: 5V (exact match required)
• Voltage - Breakdown (Min): 6.4V (exact match required)
• Voltage - Clamping (Max) @ Ipp: 9.2V (exact match required)
• Current - Peak Pulse (10/1000µs): 44.6A (exact match required)
• Power - Peak Pulse: 400W (exact match required)
• Package / Case: DO-214AC, SMA (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Bidirectional Channels: 1 (exact match required)

Substitute parts are grouped into two categories:

Direct Substitutes: Parts with identical electrical specifications and package configuration, differing only in manufacturer or product status (active vs. obsolete).

Similar Parts: Components with the same reverse standoff voltage and package but different clamping voltages, peak pulse currents, or power ratings. These require circuit-level evaluation before substitution.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Recommended for Pin-for-Pin Replacement):

SMAJ5.0CA (MDD), SMAJ5.0CA-TP (Micro Commercial Co), and TV04A5V0JB-HF (Comchip Technology) are direct electrical equivalents to the CD214A-T5.0CALF. All three parts maintain identical reverse standoff voltage (5V), clamping voltage (9.2V), and peak pulse current (44.6A) specifications. These parts are active products with current manufacturing status and full RoHS3 compliance. SMAJ5.0CA-TP offers the widest operating temperature range (-55°C ~ 175°C) and is suitable for applications requiring extended thermal performance.

Similar Parts (Require Circuit Evaluation):

SM4T6V7CAY (STMicroelectronics) and SMA6J5.0CA-TR (STMicroelectronics) share the same 5V reverse standoff voltage and DO-214AC package but feature higher clamping voltages (13.4V) and significantly higher peak pulse currents (174A and 298A respectively). SMAJ5.0CA-TR (STMicroelectronics) also exhibits 13.4V clamping voltage with 174A peak pulse current. These parts are suitable only when circuit design permits higher clamping voltages and can benefit from increased current handling capability. Both STMicroelectronics parts carry AEC-Q101 automotive qualification where applicable.

All substitute candidates are ROHS3 compliant and carry EAR99 ECCN classification matching the original part.

Frequently Asked Questions (FAQ)

Q: Can SMAJ5.0CA directly replace CD214A-T5.0CALF?

A: Yes. SMAJ5.0CA is a direct electrical equivalent with identical reverse standoff voltage (5V), clamping voltage (9.2V), and peak pulse current (44.6A). Both use the DO-214AC (SMA) package. The primary difference is manufacturer (MDD vs. Bourns) and product status (active vs. obsolete). Verify PCB layout compatibility before substitution.

Q: What is the difference between SMAJ5.0CA-TP and SMAJ5.0CA?

A: Both parts are electrically identical with 5V reverse standoff and 9.2V clamping voltage. SMAJ5.0CA-TP is manufactured by Micro Commercial Co and rated for -55°C ~ 175°C operating temperature, while SMAJ5.0CA (MDD) is rated -50°C ~ 150°C. SMAJ5.0CA-TP provides superior thermal performance for extended temperature applications.

Q: Can SM4T6V7CAY or SMA6J5.0CA-TR be used as substitutes?

A: These parts share the same 5V reverse standoff voltage and DO-214AC package but feature 13.4V clamping voltage (versus 9.2V) and significantly higher peak pulse currents (174A or 298A versus 44.6A). Substitution is possible only if circuit design permits higher clamping voltages. Higher clamping voltage may affect downstream component stress levels. Perform circuit simulation before implementation.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and carry identical HTSUS classification (8541.10.0080) to the original CD214A-T5.0CALF.

Q: What packaging options are available for direct substitutes?

A: Direct substitutes (SMAJ5.0CA, SMAJ5.0CA-TP, TV04A5V0JB-HF) are available in DO-214AC (SMA) surface-mount package only, matching the original part. Tape & Reel (TR) and Cut Tape (CT) packaging options are available from specific manufacturers for production quantities.

Q: Does operating temperature range affect substitution suitability?

A: Operating temperature range should match or exceed application requirements. SMAJ5.0CA-TP (-55°C ~ 175°C) provides the widest range among direct substitutes. If your application operates within -55°C ~ 150°C, all direct substitutes are suitable. For extended temperature applications above 150°C, SMAJ5.0CA-TP is the preferred choice.
